Background:
Members of the ancient land-plant-specific transcription factor AT-Hook Motif Nuclear Localized (AHL)
gene family regulate various biological processes. However, the relationships among the AHL genes, as well as their evolutionary history, still remain unexplored.
Results:
We analyzed over 500 AHL genes from 19 land plant species, ranging from the early diverging Physcomitrella
patens and Selaginella to a variety of monocot and dicot flowering plants. We classified the AHL proteins into three types (Type-I/-II/-III) based on the number and composition of their functional domains, the AT-hook motif(s) and PPC domain. We further inferred their phylogenies via Bayesian inference analysis and …
